WRINGING AND MANGLING MACHINE.

SPECIFICATION forming part of Letters Patent No. 611,075, dated September 20, 1898.

Application filed March 14,1898. Serial ND. 673,688. (N0 model.)

To all whom it may concern;-

Be it known that I, VILLIAM MOLEAN, a subject of the Queen of Great Britain, residing at Belfast, in the county of Antrim, Ireland, have invented certain new and useful Improvements in fringing and Mangling Machines, (for which I have filed an application in Great Britain, No. 13,365, dated May 31, 1897,) of which the following is a specification.

This invention relates to wringing and man gling machines for pressing and finishing textile fabrics of all kinds; and it has for its object mainly to construct a simple and eflicient machine which will minimize the risk of accident.

The main feature of the invention is that, although revolving rollers are employed, as in similar machines heretofore in use, the operator stands on the opposite side of the machine to that on which the work is taken in by the revolving rollers. Two rollers are by preference used, and the goods to be operated upon are placed on the top of the upper roller and are carried forward and downward by said roller, being guided in their descent by means of a curved guide or its'equivalent secured to the machine and are fed in between the upper roller and the lower roller and delivered out at the front on a board or table. The guide forms, in combination, also a guide and feeder to the take of the rollers. The bottom roller is preferably made larger in diameter than the top roller, and the centers of the axles of the rollers are not in direct perpendicular line with each other, but the axle of the top roller is placed in advance of the perpendicular line through the center of the bottom roller to an extent equal to the differences of the diameters of the rollers. With this arrangement the front edge of the rollers is in a direct perpendicular line, while the bottom roller extends backward from the perpendicular line beyond the top roller to an extent equal to its extra diameter, and

thereby performs a lifting action when rotating. If desired, the rollers may be made of equal or of different diameters, and the line of the axle-centers be placed at any angle from the perpendicular to the horizontal, so as to suit the requirements in the treatment of various classes of goods.

The pressure applied to the top roller is derived from two large adjustable spiral or helical springs which act direct on the bearing-boxes of the top roller, said roller being supported when not in operation by means of adjustable wedge-bars having screw-threaded ends provided with nuts, so as to prevent the rollers coming in contact with each other, thus reducing friction and strain when the rollers are not in actual work.

The frame of the machine is composed of two cast-iron ends united by means of a castiron stay-trough.

In order that my said invention may be properly understood, I have hereunto appended two explanatory sheets of drawings, whereon-- Figure 1 is a side view, and Fig. 2 a plan, of the wringing and mangling machine. Fig. 3 is a Vertical section, to an enlarged scale, of the same. Fig. 4is a perspective view. Fig. 5 is a detail view, being a partial sectional View showing a spring pressing on the upper axlebox.

Referring to the drawings, the same reference-letters wherever repeated indicate the same parts.

The machine consists of two cast-iron side frames or ends a a, which are joined together by means of a cast-iron stay-trough b, which latter is made with lugs I), through which the bolts 0 are passed.

d e are the two rollers, the top one of which may, as shown, be smaller than the other and whose axle may be in advance of a perpendicular line drawn through the center of the bottom roller to an extent equal to the differences of the diameters of the rollers. The bearing-boxes fg of the rollers work in the guides h of the frame. Pressure is applied to the. top roller by means of spiral pressuresprings t' '5, which bear directly upon the boxes of the top roller at their lower ends and against bridges j j at their upper ends. Long screw-bolts Z pass through these bridges and are secured at their upper ends by means of nuts m and at their lower ends by means of nuts or heads 71. By screwing up or slackening the nuts m the tension of the springs can be adjusted. To prevent the top roller coming in contact with the lower one when the rollers are not in operation, the bearing-boxes of the upper roller are supported on wedgebars 0 0. These wedge-bars can be adjusted vertically in the slots 13 of the frame. The curved guide (1 is hinged at q q to a crossbar 7', which is supported at each end in the lugs s of the casings if for the springs.

u is the delivery-table, o the usual drivinggear, and w the belt.

The main feature of this invention is the fact that, as already explained, the operator stands on the opposite side of the machine to that at which the work is taken in by the revolving rollers. He places the goods upon the top of the upper roller and between it and the guide, as shown at A, the goods being carried forward and downward by the upper roller and then passing between the rollers to the delivery table or board.

The guide (1, as shown at Fig. 3, forms a guide and feeder to the take of the rollers. The curved guide is preferably provided with one or more pressure-levers a; and adjustable weights y. I do not limit myself to just the form of guide shown.

Having now fully described my invention, what I claim, and desire to secure by Letters Patent, is-

1. The combination, in a wringing or mangling machine, of a frame, rollers cl, 0, supported therein, a delivery-table on the front side of the machine, a guide pivoted above the roller (Z and extending at the rear of the machine to the entrance between the rollers, as set forth.

2. The combinationin a wringing and mangling machine of a frame, rollers fitted in the frame, means for revolving the rollers and a sheet-metal guide pivoted above the top roller and extending to the rear entrance between the rollers and serving as a guide to the material fed in between the rollers, substantially as set forth.

3. The combination in a wringing and mangling machine of a frame, two rollers fitted therein the top roller being smaller than the bottom roller and having its center in advance of the center of the bottom roller, means for revolving the rollers, and a guide q pivoted above the upper roller and extending to the rear entrance between the rollers, substantially as set forth.

4:. The combination in a wringing and in angling machine of two side frames a, a, connected together by a stay-trough I), rollers (Z, 6, carried by the frames the axles of said rollers being out of line, bearings for the rollers, springs i pressing on the bearings, means for adjusting the tension of the springs, means for revolving the rollers, and a rear guide q pivoted above the upper roller, substantially as set forth.

5. The combination of the frames a, a, the stay-trough b the rollers (Z, c, the wedge-bars 0, 0, the guide q, the pressure-springs i, the casings t for the springs, means for adjusting the tension of the springs and means for revolving the rollers, substantially as set forth.

Signed at Belfast, Ireland, this 1st day of March, 1898.

WILLIAM MOLEAN.
